Oh Guruvayurappa! The path of Karma yoga which consists of performing one's duties needs to be practiced for a long time. The path of Gyaana yoga which consists of knowing the Brahman, as explained in the Upanishads, is very difficult for the mind yields results only in the distant future. O Lord! Bhakti yoga which is of the nature of pure love to Thee.So it is the sweetest and the noblest and hence most beneficial and more satisfying to our minds.
